Ridley Scott's 1982 sci-fi masterpiece was ranked the fourth best movie of all time in an online survey and is given the deluxe treatment in this four-disc collector's edition. Viewers can choose from the original two-hour U.S. theatrical cut, the international version, and two "director's cuts" (1992, 2007), which include the controversial "unicorn" sequence. Three commentary tracks are offered: one by Scott, another by the screenwriters and producers, and a third by the Oscar-nominated production designer and special effects supervisors, and visual futurist Syd Mead. Other bonuses include a 3½-hour making-of documentary and 90 minutes of featurettes, deleted and alternate scenes, interviews, and screen tests.
